NAME

       vme_manual_setup,  sys_attrs_vba_vipvic	-  Describes how to set up VIP/VIC-based Alpha VME systems for use on the VMEbus, including how to
       modify attributes of the vba_vipvic kernel subsystem

DESCRIPTION

       VMEbus setup allows you to run the operating system on the following VIP/VIC-based AXPvme and Alpha VME systems:

	      AXPvme single-board computers (SBCs) Alpha VME 4/224 and 4/228 SBCs Alpha VME 5/352 and 5/480 SBCs Alpha VME 2100 system

       For information about installing the operating system on the listed systems, see the Installation Guide.

       For information about setting up UNIVERSE II-based Alpha VME systems for use on the VMEbus, see the sys_attrs_vba_univ(7) reference page.

       See System Configuration Supplement: OEM Platforms for detailed information about the use of the VMEbus on the  listed  systems,  including
       the following topics: Configuring the vba_vipvic subsystem Configuring VMEbus A32 and A24 address spaces Configuring the VMEbus A16 address
       space Configuring VMEbus interrupts Using VMEbus hardware byte-swapping modes Sharing memory between big endian and little  endian  proces-
       sors  Performing VMEbus slave block transfers Performing VMEbus master block transfers with local DMA Using the realtime interrupt-handling
       routine rt_post_callout

       The defaults supplied for various VMEbus parameters are listed below.  The default values specified should provide proper VMEbus  operation
       for  most applications.	Be careful when modifying these values;  not all adapters support all fields.  Parameter       Default	   Meaning

       Lmt_DMA_Wrt     0	   No DMA write limit

       Frce_Hw_DMA     0	   Do not force hardware DMA engine fo
				   SMP system

       A32_Base        0x08000000  A32 inbound DMA window base address

       A32_Size        0x8000000   A32 window size (128 MB)

       A24_Base        0x00C00000  A24 inbound DMA window base address

       A24_Size        0x400000    A24 window size (4 MB)

       A16_Base        0x00000100  A16 interprocessor communication base
				   address

       A16_Mask        0x00000000  A16 interprocessor communication mask

       A24_A32_Ovrlap  1	   Inbound A24/A32, if same space, overlap

       The following VMEbus interrupt parameters provide initial defaults that are later overwritten by system priority level  (SPL)  values  sup-
       plied  by the platform.	See the values listed in System Configuration Supplement: OEM Platforms, or query the values at run time using the
       command sysconfig -q vba_vipvic.  Parameter	 Default     Meaning  --------------------------------------------------------------------
       Irq0_SPL 	3	   VMEbus IRQ level to system SPL map
